The game takes 20 seconds to generate a 256×64×256 map.Chunks are loaded in order of their proximity to the player.Chunks are 16×16 blocks instead of 8×8 because 8×8 chunks decreased performance.The size of each chunk was 16×16 blocks.Take about 1⁄ 10 of a second to generate each.Its texture at this time would later be repurposed for cobblestone.Made with the same graphics from Notch's game RubyDung.Grass appears on fully lit tiles on the top 7 layers of the map.Made with the same graphics from RubyDung.
